Question 1
What is the effect of forward bias on junction current?
- It reduces current
- It allows current to flow freely
- It blocks current
π‘ Hint: Think about the structure of the junction.
Question 2
True or False: In reverse bias, the collector current flows freely.
- True
- False
π‘ Hint: Consider the impact of the depletion region.

Challenge Problems
Push your limits with challenges.
Question 1
If a BJT has a forward bias voltage of 0.7V and the saturation current is 10 microamps, derive the collector current at this voltage assuming exponential behavior.
π‘ Hint: Identify what I_S and the exponential factor would imply.
Question 2
Calculate how a decrease in base width to half affects the transistor's current gain assuming all other variables remain constant.
π‘ Hint: Consider the relationship between base width and carrier life.
